#0 => Ólafur R. Helgason - Chord: A Scalable Peer-to-peer Lookup Protocol for..

For our first meetup Ólafur R. Helgason will present and lead the discussion on Chord: A Scalable Peer-to-peer Lookup Protocol for Internet Applications (http://pdos.csail.mit.edu/papers/ton:chord/paper-ton.pdf).

We hope to see as many as possible and I hope we can make these meetups a regular thing.

Abstract
A fundamental problem that confronts peer-to-peer applications is the efficient location of the node that stores a desired data item. This paper presents Chord, a distributed lookup protocol that addresses this problem. Chord provides support for just one operation: given a key, it maps the key onto a node. Data location can be easily implemented on top of Chord by associating a key with each data item, and storing the key/data pair at the node to which the key maps. Chord adapts efficiently as nodes join and leave the system, and can answer queries even if the system is continuously changing. Results from theoretical analysis and simulations show that Chord is scalable: communication cost and the state maintained by each node scale logarithmically with the number of Chord nodes.

Bio
Ólafur is currently the VP of Engineering at OZ. He received his PhD in Computer Science from KTH. At KTH he was a post-doc researcher at the Laboratory for Communication Networks researching opportunistic networking and mobile wireless systems. Before going to KTH he was a researcher and teacher at Reykjavík University focusing mainly on Computer Networks.

Details
Doors open at 18:00; the presentation will begin at 18:20; and, yes, there will be beer, water, and pizza.

After Ólafur presents the paper, we will open up the floor to discussion and questions.

We hope that you'll read the paper before the meetup, but don't stress if you can't. If you have any questions, thoughts, or related information, please visit our github-thread (https://github.com/papers-we-love/papers-we-love/issues/211) on the matter.

Additionally, if you have any papers you want to add to the repository above (papers that you love!), please send us a pull request (https://github.com/papers-we-love/papers-we-love/pulls). Also, if you have any ideas/questions about this meetup or the Papers-We-Love org, just open up an issue.
